Transport of Substances from the epidermis towards the vascular tissuesFill-in the blanks with the following choices: casperian strip, symplast pathway, xylem, plasmodesmata, apoplast pathway Water and solutes either in solution or suspension move through cells through the apoplast and symplast pathway. __________ involves movement of substances through the intercellular spaces (matrix) between cells. __________on the other hand, allows movement of substances by passing through the cell membrane entering the cytosol and transfers to another cell through the opening in the cell walls called __________. However, the presence of the __________in the endodermis before the stele where vascular tissues are found, impedes the apoplastic route, thus substances move via the symplastic route to the__________.   2.

Hi. Can u define what is stem(parts of the plant)

SITUATION: You have been taking care of your own plants for several months now. You made sure that the plants get enough water, sunlight, and minerals for them to be healthy. All of the sudden you were asked to travel to another country for a while and you needed to leave immediately. Because of this you forgot to have someone to watch over your plants. They were kept inside the house for 2 months without being watered and only a minimal amount of sunlight. Describe the state of the plant upon your return. Defend your answer based on the concepts on the light dependent reactions.

Fill in the general characteristics of the three types of plant cells.

nypothesis: B. Leaf Abscission Ethylene is the only plant hormone that is a gas. As such it can easily move from one plant to another. Your lab instructor may recruit you to help set up the following experiment. Arrange cuttings of holly shoots into two jars filled with water. Place each under a bell jar. Under one of the bell jars, also place a piece of fruit. You may choose whether or not to cut the fruit. Over the next week or two observe and compare the two sets of holly cuttings. 3. What differences do you anticipate observing? 4. Formulate your hunch into a null and an alternative hypothesis: a. Null Hypothesis: b. Alternative Hypothesis: C. Effects of Gibberellic Acid on Dwarf Corn Dwarf corn (Zea mays) plants have been grown for you. These plants are shorter than

. The movement of hydrogen ions and sucrose molecules in the same direction across the plant cell membrane, at the same time, using the hydrogen ion gradient as an energy source, is an example of: antiport movement symport movement uniport movement all of the above none of the above

Growers often wrap potted plants in plastic sleeves prior to shipping. If plants remain in these sleeves too long, their leaves curl and fall off. Imagine you are working at a garden center and have been asked to make a presentation to a local garden club.Unit 5 DQ Question: Explain the processes that may cause the leaves to drop and fall.

B. LEAF ADAPTATION The main function of the leaf is in the processes of photosynthesis and transpiration. Apart from these functions, leaf is sometimes adapted to perform other functions. Examples of leaf adaptations are for: a) Support, which could be seen by the presence of tendrils b) Catching insects, by having cup-liked shape of hairs sensitive to touch c) Reproduction, by having meristematic cells able to produce new shoots that will go on to become new individual plants d) Food and water storage, especially found in plants living in dry areas where water is scarce (for example succulent plants, having leaf storing food and water) e) Floatation, for plants living on the water surface, their leaves in general will have air openings on tissues (used for floating) usually found on leaf petiole f) Protection, by having leaves completely or partially modified as thorns Instruction: a) 1. Search for ONE plant species with the following leaf adaptations 2. Give their scientific names…

II. Pathway of Water. Place the following phrases in correct order based on the pathway of water from the soil, into the plant and to the atmosphere. (2 points each) Evaporation of water from the stomata of the leaves Up the xylem in the stem Movement across root cells Movement of water molecules to the roots Movement of water across leaf cells through osmosis Stomata. Use the word bank to fill in the blanks. carbon dioxide Open close Oxygen epidermis Flaccid guard cells Turgid Water in Soil III. water pores transpiration glucose Atmosphere

Diagram 1: Cross Section of a leaf-cells and structures. cuticle -upper epidermis palisade layer chloroplasts vascular bundle spongy mesophyll -intercellular chamber -lower epidermis stoma A possible explanation to explain the presence of the stoma structure would be that it stores extra water the leaf does not need. allows a passageway for gasses to enter and exit the leaf makes sugar needed by the cells. O maximizes the absorption of sunlight energy O O O O

a) Transport System b) Digestive System c) Respiratory System d) Excretory System Choose any 2 of the following topics/systems above, discuss how does the animal and plant (name the animal and plant) works in maintaining their function in an environmental stress (name the stress) mentioned above.

Which of the following membrane activities requires energy from ATP hydrolysis?  Group of answer choices water uptake of plants from roots to shoots movement of water using aquaporin absorption of dissolved nutrients in the small intestine transport of oxygen through the phospholipid layer

#15: The dark line at the tip of the arrow could be two different tissues, name and give the function for either of them. #16: What part of the plant is this picture taken from?

Answer the following wu

Give the similarities and differences of plants and animals in terms of its: Reproduction, development, nutrition, gas exchange, transportation/ circulation, regulation of the body fluids, chemical and nervous control, immune systems, and sensory and motor mechanisms.

Direction: Explain the following in paragraph form consists of at least five sentences  Stomates must be open for evaporation to occur. Going back to the last lesson, how plant transport and gas exchange happens?

Plants that live on and in (submerge or floating) water are called aquatic plants. They are plants that have successfully adapted in aquatic habitat. They are also called hydrophytes. Aquatic plants can only grow in water and muddy soil.
